10 Responses to Fixing the “visual editor not working” in wordpress.

I had the same problem today , after upgrading to wordpress 3.5.2, the Visual edit dissapeared. I tries – just like you – all sollution found on web. Thanks to your method now I had fixed. So, it works deleting the wp-include and re-copy it from the tar.gz archive.

Have the same problem too after upgrade to 3.2.5. Visual editor, postbox container, and the whole interface in admin post-edit not working. So, i look on the jetpack plugin. After i deact and reactivate it, the editor back to normal. I feel lucky ! 😀

Just download it from wordpress.org. You can also download the ZIP file. Remember to back up beofre launching. Download the wordpress.org version corresponding to whatever version you are running. I just renamed and uploaded the folder. Then I switched names an checked that everything worked. Easy and fast to revert if something goes wrong.

The wp-includes folder is as far as I know just static php and js files. If reverting back the original wp-includes folder don’t work then something strange must have happened.
I think php is case sensitive. May it simply be as simple as a capital letter in the wp-includes name? Is the WordPress installation heavily modified?
